ACA109-102

this configuration is a ACA aftercooler unit built on a removable straight-tube bundle for compressed air aftercooling. Hot compressed air enters the tubes while cooling water counterflows through the shell, condensing moisture for removal downstream. Its envelope centers on a 10-inch diameter shell, 108-inch shell length in a 1-pass arrangement. It carries 1/4-inch O.D. tubes. That combination is cataloged as ACA109-102. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 300°F maximum temperature. Installations range across compressed air dryer pre-cooling, compressor discharge aftercooling, and pneumatic tool and instrument air conditioning. A floating rear tubesheet lets the bundle expand freely and pull for cleaning, and full-size air connections hold pressure drop down.
